And the article was included in Chemistry – A European Journal in 2017.Related Products of 139139-80-3 The following contents are mentioned in the article:

The selective C(sp³)-H bond functionalization was an ideal and atom-economical method in organic synthesis. In this work, 2-aminopyrimidines, e.g., I were generated from a Cu-catalyzed reaction between carbodiimides and diaryliodonium salts, by cleavage of four C(sp³)-H, one C-N, and one C=N bonds in the carbodiimides. It is the first triple C(sp³)-H bond functionalization neighboring a C=N bond. The selective synthesis of 2-aminopyrimidines were controlled by the amount of the diaryliodonium salts. The novel mechanism involving a C-N formation/1,5-H shift/1,7-H shift/6π-electrocyclic ring-closing/aromatization was well elucidated by the detection of important intermediates and DFT calculations This study involved multiple reactions and reactants, such as Bis(2,4,6-trimethylphenyl)iodonium triflate (cas: 139139-80-3Related Products of 139139-80-3).

N¹– and N³-Arylations of Hydantoins Employing Diaryliodonium Salts via Copper(I) Catalysis at Room Temperature was written by Abha Saikia, Raktim;Barman, Dhiraj;Dutta, Anurag;Jyoti Thakur, Ashim. And the article was included in European Journal of Organic Chemistry in 2021.Product Details of 139139-80-3 The following contents are mentioned in the article:

Copper(I)-catalyzed N-arylation (both N¹– and N³-) of hydantoins with diaryliodonium salts as aryl partners at room temperature is reported. The transformation allows diverse scopes on both hydantoins and diaryliodonium salts delivering functionalized N³-arylated products under mild reaction conditions. The presence of hydrogens at C⁵– and N¹– position of the hydantoin does not lead to other side products. Chiral hydantoins can also be synthesized via this methodol. Sterically complicated ortho-substituted diaryliodonium salts are tolerated and delivered challenging ortho-arylated products. In addition, this strategy can also be effectively extended to N¹-arylation of hydantoins.

Described here is an efficient method to access highly functionalized arynes from unsym. aryl(mesityl)iodonium tosylate salts.
